By the time the Replacements got to their seventh album, the band was starting to wear down. The alcohol and drugs, the endless time on the road, the testy relationships with label execs, the lofty — and failed — expectations. On the album “Don’t Tell a Soul,” you can hear the world weariness setting in. Except one night, when the producer and record company people had gone home. Tom Waits joined them after midnight at the recording studio in L.A. The whiskey flowed, Waits settled in behind the B-3 organ, the band hit “record,” and for one night, alongside their kindred spirit and free from pressure, the Replacements had fun.
